Doctors who performed the procedure that led to Joan Rivers' death screwed up by not following the proper procedure before sedating her with Propofol ... this according to a New York State agency.
The Dept. of Health and Human Services examined the Yorkville Endoscopy Center, where Joan stopped breathing. The Dept. found there's no record that the staff weighed Joan before administering the Propofol ... the point being, the amount of the sedative should be based on size.
